SkillPractical Spring interview questions
Spring Boot is an open-source Java-based framework. Spring Boot is a utility for setting up an application quickly by automating the configuration procedures and speed up the process of building and deploying Spring Boot applications. It is easy to create production-ready applications using Spring Boot through embedded server(tomcat).
Prerequisites
Maven or Gradle (For this project maven is used) - https://www.oracle.com
Java (Recommended 1.8 version or greater version) – https://maven.apache.org
IDE (It can be anything like sts, eclipse, IntelliJ, etc. but this project explained with eclipse as IDE).
Basic understanding of HTTP methods i.e. GET, POST, PUT, DELETE, etc.
Basic understanding of Spring MVC.
Advantages of Spring Boot
Container fewer Deployments: In Spring Boot instead of deploying application in containers (like tomcat, JBoss, etc.) it had embedded tomcat, as a result. a) Pre-setup of container & configuration for each environment like development, production, etc. is not required. When the application is ready for deployment we only need to find an environment that is capable of running the correct version of java that our application runs. b) For application to work we need to provide some deployment descriptive so the container understands how to deploy & serve up our application which is done in XML. but in Spring Boot no longer needed deployment descriptive & web.xml file as Spring Boot contains an embedded container.
Avoids writing lots of boilerplate code, Annotations.
Web-applications architecture
Every Web-application will have a user interface (Front end) & Server-side (back end). Spring Boot is useful in the Server side. User Interface talks with Server Side and vice versa using HTTP/HTTPS Protocol.as shown in the diagram below.
